According to the CDC, "Meningitis is an inflammation of the tissue that covers the brain and spinal cord. Viral meningitis is the most common type of meningitis. It is often less severe than bacterial meningitis, and most people usually get better on their own (without treatment). However, infants younger than 1 month old and people with weakened immune systems are more likely to have severe illness".

Prevention • Wash your hands often with soap and water, especially after changing diapers, using the toilet, or coughing or blowing your nose. • Avoid touching your face with unwashed hands. • Avoid close contact such as kissing, hugging, or sharing cups or eating utensils with people who are sick. • Cover your coughs and sneezes with a tissue or your upper shirtsleeve, not your hands. • Clean and disinfect frequently touched surfaces, such as toys and doorknobs, especially if someone is sick. • Stay home when you are sick.
